Soil From Wikipedia, the free encyclopedia Jump to: navigation search Loess field in Germany Surface-water- gley developed in glacial till , Northern Ireland For other uses, see Soil (disambiguation) Soil is the naturally occurring, unconsolidated or loose covering of broken rock particles and decaying organic matter (humus) on the surface of the earth , capable of supporting life In simple terms, soil has three components: solid, liquid, and gas. The solid phase is a mixture of mineral and organic matter . Soil particles pack loosely, forming a soil structure filled with voids. The solid phase occupies about half of the soil volume. The remaining void space contains water (liquid) and air (gas). Contents Characteristics Formation In nature Uses ... edit Characteristics Darkened topsoil and reddish subsoil layers are typical in some regions. Soil color is the first impression one has when viewing soil. Striking colors and contrasting patterns are especially memorable. The Red River in Mississippi carries sediment eroded from extensive reddish soils like Port Silt Loam in Oklahoma . The Yellow River in China carries yellow sediment from eroding loessal soils.

The Topic: Soils Easier - Soil is the loose top layer of our planet's crust. It is dirt or earth in which plant life can grow. Harder - Soil covers a major portion of the earth's land surface. It is an important natural resource that either directly or indirectly supports most of the planet's life. Life here depends upon soil for food. Plants are rooted in soil and obtain needed nutrients there. Animals get their nutrients from plants or from other animals that eat plants. Many animals make their homes or are sheltered in the soil. Microbes in the soil cause the breakdown and decay of dead organisms, a process that in turn adds more nutrients to the soil. Soil is a mixture of mineral and organic materials plus air and water. The contents of soil varies in different locations and is constantly changing. There are many different kinds and types of soils. Each has certain characteristics including a specific color and composition. Different kinds of soils support the growth of different types of plants and also determine how well that plant life grows. Soil is formed slowly, but can be easily destroyed. Therefore, soil conservation is important for continued support of life.

Soil makes up the outermost layer of our planet. Topsoil is the most productive soil layer. Soil has varying amounts of organic matter (living and dead organisms), minerals, and nutrients. Five tons of topsoil spread over an acre is only as thick as a dime. Natural processes can take more than 500 years to form one inch of topsoil. Soil scientists have identified over 70,000 kinds of soil in the United States. Soil is formed from rocks and decaying plants and animals. An average soil sample is 45 percent minerals, 25 percent water, 25 percent air, and five percent organic matter. Different-sized mineral particles, such as sand, silt, and clay, give soil its texture. Fungi and bacteria help break down organic matter in the soil. Plant roots and lichens break up rocks which become part of new soil.

People who study soil seek to comprehend fundamental global surface processes on multiple scales that impact ecosystems functioning and environmental health. Our mission is to provide instruction, research and extension leadership in application of soil chemistry, physics, biology and pedology principles to economic and environmentally sound land use. Our programs are designed to improve basic understanding and practical management of soil resources in natural, agricultural and urban ecosystems. We proactively implement the Wisconsin Idea of outreach to the extended community to provide all generations with an appreciation of soil as a natural resource.

19. Great Plant Escape - Soil Types People describe soil types in all kinds of ways such as heavy, light, sandy, clay, loam, poor or good. soil scientists describe soil types by how much sand, http://www.urbanext.uiuc.edu/gpe/case2/c2facts2.html

Soil Types People describe soil types in all kinds of ways such as heavy, light, sandy, clay, loam, poor or good. Soil scientists describe soil types by how much sand, silt and clay are present. This is called texture . It is possible to change the texture by adding different things. Changing texture can help in providing the right conditions needed for plant growth. Sand is the largest particle in the soil. When you rub it, it feels rough. This is because it has sharp edges. Sand doesn't hold many nutrients. Silt is a soil particle whose size is between sand and clay. Silt feels smooth and powdery. When wet it feels smooth but not sticky. Clay is the smallest of particles. Clay is smooth when dry and sticky when wet. Soils high in clay content are called heavy soils. Clay also can hold a lot of nutrients, but doesn't let air and water through it well. Particle size has a lot to do with a soil's drainage and nutrient holding capacity. To better understand how big these three soil particles are, think of them like this. If a particle of sand were the size of a basketball, then silt would be the size of a baseball, and clay would be the size of a golf ball. Line them all up, and you can see how these particles compare in size.
